neoadjuvant chemotherapy for patients with squamous cell carcinoma of the penis

Conditions: Penile Cancer

Summary: primary objective: -to evaluate the feasibility and efficacy of multimodality treatment (neoadjuvant chemotherapy prior to extirpative surgery) for clinical stage txn2-3m0 squamous cell carcinoma of the penis.

before treatment starts, participants will have a complete exam, including blood and urine tests. a ct scan of the abdomen and pelvis will be done. participants will have a chest x-ray, bone scan, and an ekg (heart test). a special heart function test may also need to be done in some participants. if necessary a biopsy of enlarged lymph node(s) will be obtained prior to treatment. blood tests will be repeated once a week during treatment. ct scans of the abdomen and pelvis and a chest x-ray will be done after 2 treatments with taxol, ifosfamide, and cisplatin. these will also be done before surgery. the drugs taxol, ifosfamide and cisplatin will be given through a catheter (plastic tube) placed in a vein in the arm or under the collarbone. taxol will be given over 3 hours the first day of the treatment cycle. to prevent an allergic reaction, before the taxol is given, the participant will receive three drugs. these are dexamethasone, diphenhydramine, and either cimetidine or ranitidine. after taxol, ifosfamide will be given over 2 hours every day for the first three days of the treatment cycle. to prevent possible irritation of ifosfamide to the bladder, participants will also receive mesna through the plastic catheter. mesna will be given both before and after ifosfamide every day. mesna is not chemotherapy. it is a medication to prevent side effects of ifosfamide into the bladder. every day for the first three days of the cycle, and after ifosfamide is given, participants will also receive cisplatin through the catheter at a steady rate over 2 hours, along with mannitol and salt water to flush the kidneys. this treatment will be given in the hospital and will require staying in the hospital for 3-4 days. it will be repeated for a total of 4 times; once every 21 days, if the participant has high enough numbers of white blood cells and platelets. participants may be given injections of g-csf under the skin once a day for up to 7 days (days 6-12 of the cycle) to bring the white cells up faster after the chemotherapy. this will also lower the risk of severe infections. after completing 4 treatments of chemotherapy, participants will have blood and urine tests, a chest x-ray to learn the response of the tumor to the chemotherapy. they will also have a ct scan of the abdomen and pelvis. participants who have a response to the chemotherapy, or show no sign of new spread of the cancer to other parts of the body, will then have surgery. surgery will be done to remove the tumor. the lymph nodes in the groin will be removed. the pelvic lymph nodes may also need to be removed. how much tissue is removed depends on how far the tumor has spread. the surgeons will explain the specifics of the surgery in a separate consent form. after completion of the treatment, physical exams, ct scans, chest x-rays, blood tests, and urine tests will be done every 3 months for 2 years. they will then be done every 6 months. these procedures can be done by a physician at m. d. anderson or by the participant's own doctor. if the participant's doctor does it, the information will need to be forwarded to the doctors at m. d. anderson. participants will be expected to come to m. d. anderson or to their respective participating urologist/medical oncologist at least once every 6 months for a check-up. this is an investigational study. the fda has approved taxol, ifosfamide, cisplatin, and mesna. up to 40 participants will take part in this study. all will be enrolled at m. d. anderson.
